Title: Method for making a prolineboronate ester
Inventor: SNOW ROGER
IPC: C07D207/00
Filed: 1992-11-19
Abstract: A method for the preparation of esters of prolineboronic acid is described. An N-protected pyrrole (I) is lithiated at the 2-position. The lithiated species (II) is reacted with trialkylborate, to yield a protected pyrrole-2-boronic acid (III). This is reduced to form a protected prolineboronic acid (IV), which, in turn, is reacted with a diol to yield an ester (VI). With the boronic acid moiety protected by the ester group, the protecting group on the nitrogen is removed, yielding the desired prolineboronic acid ester (VII). In an alternative synthesis, a protected pyrrolidine (VIII) is lithiated at the 2-position to yield a protected 2-lithio-pyrrolidine (IX). This is reacted with trialkylborate to yield the intermediate IV. The prolineboronic acid esters so produced have a chiral center to the boron atom. Also disclosed are methods for resolving enantiomers. The final products can be coupled to activated carboxylic acids, to yield peptides having a prolineboronic acid ester, instead of an amino acid, at the C-terminus.  These boronic acid peptide analogs are useful for inhibiting biologically important proteases. Several methods for removing pinanediol from pinanediol boronate esters are also disclosed.

Patent CA-2140489-A1 (CA)
Inventor: ALPERS HELMUT A
IPC: B67D3/00
Filed: 1995-01-18
Abstract: A frozen dessert dispensing apparatus is provided with a metering chamber having a predetermined volume into which a frozen dessert product is issued at a uniform constant rate from a bulk source.  The time period required to fill the chamber volume determines a characteristic viscosity valve of the dessert product which is advantageously used to time the flow of additional frozen dessert product from the source into and through the chamber to a selected point.  The total time required to dispense a desired volume is based upon the viscosity measurement.  A reciprocating piston arrangement provides gating of the frozen dessert product from the bulk source when in a first position and further acts to extrude frozen dessert product from the metering chamber when set in motion under the command of a controller.  The piston arrangement includes a compressible plunger portion which deforms as necessary to prevent accidents or other mishaps from occurring in pinch-off regions of the apparatus.

Filed: 1995-10-04
Abstract: A tunable quadrature phase shifter including two branches each constituted by the cascade connection of a filter, an amplifier and a summing circuit, and two cross-connections constituted by amplifiers interconnecting the filter of one branch to the summing circuit of the opposite branch. An accurate 90 degrees phase shift between the two output signals is obtained by controlling the tail currents of the four amplifiers.        The phase shifter used in mobile telecommunication transceivers may be easily and accurately tuned because the signals used in the summing circuits all have a similar amplitude. It is further adapted to operate with only 3 Volt battery supply as used in wireless phones.        The bandwidth of the amplifiers is increased by using double differential pair amplifiers which behave as cascode arrangements.
